Now that we have copied those three initial files, suppose a new file was just dropped in that folder, and we only want to transfer the new one and not the other three that have already been copied over. This further shows that an operation actually occurred rather than just the listing, as shown first. You may also note that there is a percentage complete next to each file and, at the end, a speed calculation. This time, we can see that our three files copied over successfully. Ok, now that we know our copy command will do what we want, let's copy all of those files over to the destination directory. *.* /L /DCOPY:DA /COPY:DAT /R:1000000 /W:30 Copy All Files From a Source Directory to a Destination Remember that the command above actually runs with the following options by default. Although you may see the Copied header show 3, if you actually browse to the location, you will find that nothing has actually been copied. robocopy C:\Source C:\Destination /LĪs you can see from the above screenshot, there are three files that we intend to copy to the destination location. This is done using the /L command, as seen below. By using some simple switches, in conjunction with your intended switches, you can see what would happen before actually performing the command. So now that you know a few of the options available to Robocopy, what are some of the most common operations that we can do? Verification of the File Transfer Operationīefore running a complicated file transfer operation, it's important that know that Robocopy will do what you expect it to do. /W:30 - The wait time between retry attempts, default is 30 seconds./R:10000000 - Number of times to retry on failure, default is 1 million./COPY:DAT - Default file copy options.Data and attributes (but not timestamps). /DCOPY:DA - Default directory copy options.These translate into the following set of commands: It's important to note that when running simple Robocopy commands, there are a set of default options used. /B - Use backup mode, which uses SeBackupPrivilege and SeRestorePrivilege privileges to backup files that normally require Administrative rights./Z - Use restartable mode in case the file transfers are interrupted. ![]() ![]()
